Specification of Letters Patent. Patented Mam'. 24h, 1914i. Application tiled October 8, 1912. Serial No. 724,539. v

To all 'whom t may concernv Be it known that I, JACOB KAUFMANN, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have .invented certain new and useful Improvements inl Loom-Harness, of which the following is a specification..

My invention relates to loom harness, and more particularly it relates to the formation of the individual heddles for controlling the warp ends, whereby said'heddles may be readily and easily successively selected for the purpose of inserting the warp ends in their respective heddles,

My invention contemplates a novel formation of heddles which are made of thin flat metal or wire, it heretofore having been found quite diticult to readily and rapidly successively select the individual heddles of this type for the purpose of drawing in or entering the warp ends through the eyes thereof.

The obj ect therefor of my invention is to provide heddles of the aforesaid type with means whereby certain portions thereof will be maintained separated so that the heddles may be selected quite readily.

The nature and characteristic features of my invention will be more readily understood from the following description, taken in connection with the accompanying drawings forming part hereof, in which- .f

Figure 1 is an elevation of a portion of a harness frame having heddles embodying the main features of my present invention shown mounted therein. Fig. 2 is a transverse horizontal section, enlarged, taken on the line 2 2 of Fig. 1, illustrating how certain portions of the heddles are maintained separated a uniform distance from each other whereby the heddles may be successively selected for the purpose of drawing in or entering the warp ends in the eyes; and Figs. 3 and l are enlarged side elevations of the upper portions of the two forms of heddles which are used conjointly in the preferred fo-rm of my invention.

Referring to the drawings, in the particular embodiment o f my invention therein shown, the harness frame comprises the usual upper and lower bars 5 and 6, which are connected by the end straps 7 in whichand 9y are mounted. The heddle frame proper may be of any preferred construction, such for example asshown and described in detail in Letters Patent No. 980,285 granted to me January 3, 1911, but it should be understood that the particular form of the heddle frame forms no part of my present invention. e

Upon the rods S and 9 the heddles are lncunted in the usual manner, and these heddles in the preferred manner of carrying' out my invention comprise two types A and B which are alternately arranged upon the rods 8 and 9 as clearly shown in Fig. 1 of the drawings. The heddle of the type A, near one of itsmortised ends, has a portion 10 which is offset slightly out of the main plane of the heddle proper, the offset being of an extent corresponding to the amount which it is desired to separate cer tain portions of the heddles for the purpose of successively or otherwise selecting the same. The longitudinal extent of the offset portion 10 may be of any desired dimension, V epending on the particular manner in which the heddles are operated upo-n during the drawing in or entering operation. The heddle'of the type B is also provided with an o'set portion 11, which extends out of the main plane of the heddle proper a distance approximately double that of the oset portio-n l0 of heddle A, and of a longitudinal extent somewhat greater than that of said offset portion of heddle A, extending both above and below the offset portion 10 of heddle A. As before stated, the heddles of types A and B respectively are arranged alternately in the harness frame as shown in Fig. 1 of the drawings, whereby there is provided a certain portion of each heddle which is spaced a uniform distance from a corresponding portion of the next vadjoining' heddle, which distance is maintained not-v withstanding the fiexible character of the heddles made from thin flat metal or wire. It will be seen by an inspection of Fig.V 1 that on account of the offset portion 11 of heddle B being of a greater longitudinal exl tent than the offset portion 10 of heddle A,

there is provided an appreciable bearing at leach end of the offset which will maintain the offset portions at uniform distances from each other the bearing points being indicated at 12, 13, 14 and 15. The lovrermost portions of the heddles may also be provided with odset portions 16 and 17 of heddles A and B respectively, and which respectively extend to the left and right for the purpose of maintaining the substantial parallel alinementof the heddles in the frame. It will be seen however, that the odsets 16 and 17 are not for the same purpose as those at the upper end as there is not necessarily provided any portion which is maintained separated from the complemental portion of both adjoining heddles.

The ends of the heddles of both types may be`mortised or otherwise formed in any desired manner for mounting on the rods 8 and 9, the particular form which has been arbitrarily selected for the purpose of illustration in the drawings being that which is more particularly shown and described in Letters Patent No. 996,650,.grantcd to me July 4, 1911, but it will of course be understood that any other desired means of mounting the heddles in the harness frame may be employed. The warp eye 18 may also be of any desired form.

It will beseen -that by the present invention there are provided flat metal heddles l each having certain portions which willbe maintained a fixed distance from the corresponding portions of each'ol the adjoining heddles, notwithstanding the flexible character of heddles of this type, so that it will be possible to employ the Well known automatic machines for entering or drawing in the warp ends through the eyes of the heddles, it having heretofore not been possible to employ these machines in connection with the dat metal heddles, and furthermore where the warp ends are drawn in by hand the operation will be greatly facilitated where heddles of the present invention are employed.

Having thus described the nature and characteristic features of my invention what I claim asy new and desire to secure by Letters Patent is y 1. In harness for looms, a plurality of heddles mounted in a suitable frame, said heddles being arranged in pairs, one. of each pair having a. portion odset out of the main each pair having a. similarly located portion odset out of the main plane of the heddle proper to an extent substantially double that of the odset portion of the other heddle.

2. In harness for looms, a plurality of heddles mounted in a suitable frame, said heddles beingzarranged in pairs, one of each pair having a portion odset out of the main plane of the heddle proper, and the other of each pair having a slmilarly located portion odset out of the main plane of the heddle proper to an extent substantially double that of the odset portion of the other heddle and of a longitudinal extent greater than that of the odset portionof the lother heddle.

3. In harness for looms, a plurality of heddles mounted in a suitable frame, said heddles being arranged in pairs, one of each pair having a portion odset out of the main plane of the heddle proper, and the other of each pair having a portion odset out of the main plane of the heddle proper to an extent substantially double that of the odset portion of the other heddle and extending above and below the odset portion of the other heddle.

In testimony whereof, I have hereunto signed my name in the nesses.
